I don't know about you, but I was a total emo kid in high school. One of my favorite bands was Saves The Day, and I still listen to them quite a lot! (Unlike Taking Back Sunday, which is more of a nostalgic or alcohol-influenced listen...) I saw this video a couple years ago and had to look it up after just listening to the album version of the song.
I just love that the cops try to stop it, all the while saying, "You guys sound great!" then letting them finish their song. After that, they even stick around and buy a CD! Ha ha ha.
I would still like to get "stay what you are" tattooed somewhere on me, as a reference to my favorite album by them. :)
